1. Troubleshooting the Outdoor Unit
1.1 Error Codes
Your Yanmar Gas Heat Pump system constantly monitors its components for any errors. In the
event that an error has occurred in a unit, the system automatically stops that unit.
When an error occurs, the remote controller connected to the indoor unit notifies you of the error
by displaying the corresponding error code while flashing the run lamp and inspection indicator.
The error codes appears also on the "hour meter" on the outdoor unit's control circuit board.
When normal, the "hour meter" displays operating hours.
